Boundary: Poverty rate, by age

The poverty rate is the percentage of people living below the poverty level or “threshold.” Each year, the U.S. Office of Management and Budget establishes a series of poverty thresholds for different family sizes and ages of household heads.

Among Boundary's residents, the poverty rate for people under 18 . . .

  • was 20.3 percent in 2020, 19.5 percent in 1999, and 13.5 percent in 1989;
  • was 20.3 percent compared to 11.6 percent in Idaho in 2020;
  • ranked 5th - from highest to lowest - out of the 44 counties in 2020.
These next data come from the U.S. Census Bureau's American Community Survey.  They are based on averages of data collected in 2016, 2017, 2018, 2019, and 2020. These estimates cannot be used to say what is going on in any particular year in the period, only what the average value is over the full period. The Census Bureau's provides 3-year estimates for counties with at 20,000 people, and 1-year estimates for counties with at least 65,000 people. We use 5-year estimates because they are available for all counties and allow comparison to other counties within the region.
The poverty rate for the youngest children, those under age 5 . . .
  • was 43.8 percent in 2016-2020 compared to 15.0 percent in 1999;
  • was 43.8 percent in 2016-2020 compared to 19.2 percent in Idaho;
  • ranked 2nd - from highest to lowest - out of the 44 counties in 2016-2020.
The rate for people 65 and over . . .
  • was 8.0 percent in 2016-2020 and 11.4 percent in 1999;
  • was 8.0 percent compared to 8.6 percent in Idaho in 2016-2020;
  • ranked 22nd - from highest to lowest - out of the 44 counties in 2016-2020.

NOTE: These ACS data for children under the age of 5 and elderly populations in poverty are estimates based on a five-year average, meaning that data gathered from 2015, 2016, 2017, 2018, and 2019 are averaged together to come up with the results shown here. There is no problem with comparing these data to census data from 2000. For a technical discussion of the "margins of error" associated with ACS estimates, please see: (
